Random amplified microsatellite polymorphism (RAMP) is a PCR-based marker which uses a combination of two classes of markers: Simple sequence repeat (SSR) and Random amplified DNA polymorphism (RAPD) markers. RAMP has been demonstrated to be a potentially valuable molecular marker for the study of genetic relationships in cultivated plant species. The objective of this study was to optimize the...
many agriculturally important traits are complex, affected by many genes and the environment. quantitative trait loci (qtl) mapping is a key tool for studying the genetic structure of complex traits in plants. in the present study qtls associated with yield and agronomical traits such as leaf number, leaf length, leaf width, plant height, stem and head diameter were identified by using 70 recom...
Objective(s): Mutations in the UGT1A1 gene are responsible for hyperbilirubinemia syndromes including Crigler-Najjar type 1 and 2 and Gilbert syndrome. In view of the genetic heterogeneity and involvement of large numbers of the disease causing mutations, the application of polymorphic markers in the UGTA1 gene could be useful in molecular diagnosis of the disease. Materials and Methods: In the...
genetic diversity among plants sprouted from seven year old clones of mulberry (morus indica var. s36) was studied using molecular markers such as issr and rapd. the clones showed significant variability in sex expression and the sprouting behavior. these changes were appeared after seven years of rigorous pruning and training (pruned once in every 3-4months). genetic diversity analysis reveale...
Aeluropus littoralis is one the most successful monocot grasses in terms of high salinity tolerance, that contains forage quality and has valuable physiological features. The goal of this study is to introduce and provide quick access to DNA-based molecular markers for valuable halophyte, Aeluropus littoralis to assessment of genetic diversity. For this, a total number of 110 EST-SSR ma...
DNA size markers (ladder) are essential tools in molecular biology, genetics and biotechnology. In this study, a simple and cost-effective method for laboratory production of DNA ladders is introduced. For this purpose, different sizes of 100 to 2000 bp DNA segments were designed using PCR technique. For producing 14 different gene fragments as DNA molecular weight markers, recombinant plasmid ...
a genetic marker is a gene or dna sequence with known localization on a chromosome. it can be de-scribed as a variation that can be measured or detected by a suitable method, and can be used subsequently to detect the presence of a specific genotype. such variations occurring at chromosomal or dna level can serve as genetic markers. the progress in development of molecular markers suggests thei...
Background & Aims: In recent years, molecular methods for characterizing genetic heterogeneity have found a major place in modern approaches. In this study, two different molecular techniques including Restriction Fragment Length Polymorphism (RFLP) and Multi Locus microsatellite typing (MLMT) were carried out in order to evaluate genetic heterogeneity among isolates of Leishmania major in Iran...
Having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. In present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and RAPD markers. Significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...
objective(s): iran is considered as one of the high-prevalence areas for β-thalassemia with a rate of about 10% carrier frequency. molecular diagnosis of the disease is performed both by direct sequencing and indirectly by the use of polymorphic markers present in the beta globin gene cluster. however, to date there is no reliable information on the application of the markers in the iranian pop...
